Hi guys - well, I had sent two GHs back on RMA, each under their own RMA number as you have to create them against the specific serial number of the device, and last week they notified me, in ONE of the RMA tickets, that one of them was shipping back to me (supposedly repaired).
The box arrived on Friday and when opened, to my surprise, both GHs, MP, charger, batteries where in the box. That is, both the one they said they were sending back and the other one which they didn't say they were sending back.
So, I used them last night. The one they said that they were sending back (and did) worked ok. Not as good as the performance of my OG GH, but I ran the session at 4.2 and finished it at 5 and the AVB was nice and brown and the vapor was acceptable. As an aside, my OG GH performance was outstanding...I would run at 4.1 and rarely needed to go above this to get nice full extraction. But, nonetheless, the performance of the returned GH was acceptable and not something I think I can send it back for improvement. All good, right?
So, then I ran the other one...my OG GH....for which they did NOT say in the RMA ticket that it was ready and that they were sending it back. Performance seems to be just as it was when I sent it. Running it max'd on 5, I got Volcano poo looking AVB at best....still more green than I would accept from any other vape and the vapor was on the thin side. Pretty much as I remember when I sent it back.
I did, upon their approval, send both GHs under the two RMAs, back in a single box. I suspect that they fixed one of them and then someone just packed up everything in the bin for my stuff back and that the other one had not been actually service. But, this is just suspicion and I do find vape performance to be a very subjective observation so I can't prove it (and can hardly remember it as it was a bit ago).
The plan for tonight is to run both with the same herb and both at temp 5 and take close up pics of the AVB. I have a cheapo USB microscope that I use to post bud shots and the like and was recently asked to take pics of ground bud and then the resulting AVB and I did so...it was very illuminating. For example, I have heard some folks distain to grind their bud as they feel that they are damaging the trichs too much. Well, in these pics, I used a BCG w fine plate and yes, you can see where they are a bit twisted up but far from being damaged or at least they are still good with me.
So, I plan to do the same with the GH AVB.
Below is some macros of LA Chocolate from GLeaf after it was ground and the AVB that resulted in my EVO at about 1 o'clock on the dial. Its easy to see in these pics whether its been fully extracted (it was def) or not. So, now on to the GH.

AVB from the EVO (love that vape)
but all the horrible stuff about the hoppers

)...
